What is the difference between traffic shaping and traffic policing?

While traffic policing is usually used to enforce a hard rate limit, traffic shaping is used to conform to that rate limit by delaying packets in a buffer.

What is QoS policing?

Published: 23 Jun 2004. As mentioned in a previous tip, policing and shaping are QoS components used to limit traffic flow. Policing drops or remarks traffic that exceeds limits, but shaping regulates the traffic back to a defined rate by delaying or queuing the traffic.

What is shaping Cisco?

About Traffic Shaping Traffic shaping regulates and smooths out the packet flow by imposing a maximum traffic rate for each port’s egress queue. Packets that exceed the threshold are placed in the queue and are transmitted later. This process is similar to traffic policing; however, the packets are not dropped.

What is traffic shaping in QoS?

Traffic shaping is a quality of service (QoS) technique that is configured on network interfaces to allow higher-priority traffic to flow at optimal levels even when the link becomes overutilized. Time-sensitive data may be given priority over traffic that can be delayed briefly, often with little-to-no ill effect.

What does Traffic Shaping do in QoS?

Traffic shaping is a quality of service (QoS) technique that is configured on network interfaces to allow higher-priority traffic to flow at optimal levels even when the link becomes overutilized.

What is QoS traffic shaping?

What is traffic shaping Cisco?

Traffic shaping allows you to control the traffic going out an interface in order to match its flow to the speed of the remote target interface and to ensure that the traffic conforms to policies contracted for it.

How does traffic policing work in Cisco QoS?

Use traffic policing to assign packets to a QoS group. The router uses the QoS group to determine how to prioritize packets within the router. Traffic can be marked without using the Traffic Policing feature. If you want to mark traffic but do not want to use Traffic Policing, see the “Marking Network Traffic” module.

How does the QoS Group work in a router?

The router uses the QoS group to determine how to prioritize packets within the router. Traffic can be marked without using the Traffic Policing feature. If you want to mark traffic but do not want to use Traffic Policing, see the “Marking Network Traffic” module.

How is class based policing used in Cisco router?

The router uses the QoS group to determine how to prioritize packets. Traffic can be marked without using the Class-Based Policing feature. If you want to mark traffic but do not want to use class-based policing, see the “Marking Network Traffic” module.

What kind of traffic shaping does Cisco use?

Cisco recommends class-based shaping and distributed shaping, which are configured using the modular QoS CLI. The following diagram illustrates how a QoS policy sorts traffic into classes and queues packets that exceed the configured shaping rates.
